He said: "The chief executive was appointed at a time of significant staff

upheaval and when morale was at its lowest.

"Considering the task before him, Colin has exceeded all expectations. In fact, during the last four years he has excelled and the performance of this authority is a reflection of his own."

Mr Cheesman, 55, who lives in Chester, joined the council in 1973 as an assistant county secretary and subsequently served as a director of the chief executive's office and group director of both support services and information and leisure services.

A solicitor and member of the Law Society, he was educated at Liverpool University and at the College of Law in Guildford.

Mr Cheesman said: "A new chief executive could not have a stronger foundation on which to build for the future. My successor will have a flying start and the opportunity of one of the best jobs in local government."

He added: "Cheshire's exceptional performance is due more than anything else to the commitment of its staff.

"Day in and day out they give their best and very often much more than could be reasonably required of them."

It is not yet known whether Mr Cheesman intends to retire or take up a post elsewhere.

Cheshire County Council will advertise the post internally and externally and hopes to make an appointment in time for Mr Cheesman's successor to take over when he leaves in July.
